Title: Colour television signal-separating system
IPC: H04N9/78
Filed: 1956-12-14
Abstract: 843,499. Television. STANDARD TELEPHONES & CABLES Ltd. Dec. 14, 1956 [Dec. 16, 1955], No. 38284/56. Class 40(3). [Also in Group XL(c)] Relates to an arrangement for separating the luminance component from the chrominance and sound components of a composite colour television signal in a receiver utilizing the intercarrier-sound system wherein the video components consist of amplitude modulated signals, whereas the sound components consist of frequency modulated signals. As shown, a composite signal in accordance with N.T.S.C. standards is applied via a sound trap 2 to the I.F. amplifier 1, whose frequency response, Fig. 1, will correspond to the curve 3, in which the sound carrier of 41.25 mc/s. is severely attenuated with respect to the luminance and chrominance components. The output of the I.F. amplifier is applied via closely coupled transformer windings 11, 12, to a luminance circuit 6, and via a winding 13, which is loosely coupled with the windings 11 and 12, to a chrominancesound circuit 7. The winding 12 is tuned to some frequency of the luminance component, e.g. 45.75 mc/s., and the winding 13 is tuned to the frequency of the sound component, i.e., 41.25 mc/s. In this way the sound signal is effectively removed from the luminance circuit as shown by curve 13a, Fig. 2, and Fig. 3, and the attenuation of the sound signal prevents cross-hatching in the picture due to 920 kc/s. beats produced by heterodyning of the 4.5 mc/s. sound signal with the 3.58 mc/s. chrominance signal. Similarly, the luminance signals are attenuated in the chrominance-sound circuit 7, the tuned circuit 10, 13, passing the chrominance signals and the sound carrier, the sound carrier rising in amplitude with respect to the chrominance portion, Fig. 4. The circuits 2, 12 and 13 are arranged so that the relationship between the luminance and sound signals in the circuit 7 is such that heterodyning of the frequency modulated signal at relatively low amplitude with the amplitude modulated video signals will result in the production of a 4.5 mc/s sound signal having negligible amplitude modulated video components. A circuit comprising a resistor 15 in shunt with an inductance 16 and stray capacitance 17 provides peaking in the region of the chrominance signal and is arranged to effectively short circuit any luminance components which may have been passed by the detector 9. The output of the circuit 7 provides both sound and chrominance signals which are separated by subsequent circuits.

Title: Method of making lined containers
Inventor: JACKE RAYMOND EDWARD
IPC: B65B51/22
Filed: 1962-10-16
Abstract: 1,023,034. Lined containers; packaging-machines. REYNOLDS METALS CO. Oct. 16, 1962, No. 39183/62. Headings B8C and B8P. [Also in Division B6] A lined container for liquids comprises a stiff box with wall portions 40, 41, 42 and 43 and top and bottom portions formed by flaps hinged thereto, the two opposite flaps 45, 47 on the front and rear wall portions having a combined length less than the distance between said front and rear walls, and a liner having a non-metallic outer surface heat-sealed to the bottom, top and wall portions and an inner metallic surface 16 heat-sealed to itself along bottom, side and top seams, the top seam 60 being disposed above and between said top flaps 45, 47 and beneath each of the other side flaps. The liner is formed of the inner metallic layer, an outer adhesive-pervious layer and an intermediate layer of adhesive. The container is formed by feeding the liner material from a roll 116 to a machine for perforating parts of the metal foil layer to aid sealing and the liner is then fed to a folding and sealing machine 158 to form a continuous sleeve which is cut into the required length by a cutter 170 and then placed into stacks 118. The liner sleeves 118 and flat carton blanks 174 are fed together on to belts 180, 182 with the liner on wall portions 42, 41 before the wall portions 40, 43 are folded over and glued by machine 122. The liner and carton are then passed to heat sealing means to bond the liner to the carton. Since it is desirable to pull the pleats 30, 32 (Fig. 12, not shown) apart to relieve stresses which might rupture the liner the carton is flipped before passing to the second heat sealing machine by an apparatus such as that shown in Fig. 19. The leading edge 302 of the carton abuts a plate 312 while the rollers 304, 310 continue to push the carton until the corner 324 is picked up by rollers 308, 310 for feeding to the second sealing means. The cooled assembled container is then fed to machine 140 where the cartons are opened up and sealed at one end preparatory to filling in the zone 334. The ends are closed by folding in flaps 45, 47 together with the liner thus forcing the flaps 13, 14 horizontal and forming an elongated fin upstanding from the faces of the flaps. A heat sealing means is passed along the fin (Fig. 28, not shown) to seal the two opposing faces and then folded longitudinally and re-sealed to form a double seam. The two flaps 13, 14 are folded over each other and are held in place either by an overwrap or a simple adhesive means before passing to conveyer 142 for storage.
